Can't log into my Tumblr account

Whenever I enter my Tumblr credentials the app tells me that either my user name or password is wrong -- which they are not...! I've been trying on and on, hoping it was just a temporary glitch, but it's just not working...! :(

If you're having trouble connecting to Tumblr don't have any non-letter characters in your Tumblr screenname or password, then you're likely running into an issue we've been having with the Tumblr API. As Kevin's already said, we're trying to track down this problem with the Tumblr folks, so please hang in there for now. See this thread in our Known Issues forum to read more:

Since this problem stems from Tumblr's API (which we have no control over), we've been actively working with Tumblr to resolve this issue. The guidance we've received is to encourage users to try logging in again in a few minutes. This only applies to people who have already verified they don't have an ampersand in their password (in which case, that's a separate problem explained here: http://instagram.zendesk.com/entries/....

Please contact Tumblr's support team if you're still unable to log in after waiting a few minutes and trying again -- they can be reached at support@tumblr.com

Sorry most of you are still having trouble logging in to Tumblr. We got word from them over a week ago that they believed this issue with their API had been fixed, but it seems the bug is still present. Since this is an issue with their API (which Instagram has no control over), the best thing to do at this point is to email Tumblr's support team so that they can better understand the problem: support@tumblr.com

Again, the guidance we've received from Tumblr is to encourage users to try logging in again in a few minutes if the first attempt doesn't work.
